ATTORN EY PatentedMar. 19, 1940 UNITED STATES PATENT OFFICE FASTER- FOR NEWSPAPER PRESSESI Eugene P. Doyle and Leo F. Long, Toledo, Ohio Application February2,1938, Serial No. 188,216 7 8 Claims. (01. 2422-43) This inventionrelates to pasters for newspaper presses in which a continuous webofpaper is drawn from a roll by the press and, substantially when the rollis exhausted, a web from a new or .5 fresh roll is adhesively connectedto the web from the previous roll so that an uninterrupted web of Afurther object is to produce a simple and efficient timing device forpasters of the above character in which the adhesive strip on the paperroll which is rotating at press speed, first engages the traveling paperweb when the roll advances into contact with the web.-

A still further object is to provide a drive for the reel with a memberinserted between. the convolutions of the paper roll which isinstrumental in rendering the drive effective.

Other objects and advantages of the invention will hereinafter appearand for purposes of illustration but not of limitation, an embodimentoithe invention is shown on the accompanying drawings in which Figure 1 isan end elevation of the reel for the paper rolls showing particularlythe roll driving means and switch for operating the reel motor;

comprises a reel it which is mounted for rotating movements on asuitable standard H. The reel in this instance has three arms a, b, andc, the arms b and c in this instance supporting fresh rolls i2 and i3respectively of paper or dinarily used for newspapers and the arm a.supporting a substantially exhausted roll M of paper. The web :5 leadingfrom the roll l4 extends upwardly to a' relatively soft guide roll i5aand from thence passes in a suitable manner to the newspaper press (notshown), the fresh roll 12 being substantially in the position prior tosplicing or adhesively connecting the end of the roll 2 to the web l5,it being understood that substantially upon effecting the paster. thereel H) is rotated ina clockwise direction (Figure 1) so that the rolll2 will be in the position shown by the roll I A on the drawings, suchmovement being efiected by an electric motor l6 having a Worm and wheelconnection I! with the reel.

Before the paster or splicing is accomplished, the next succeeding oroncoming roll of paper, such as the roll !2, is rotated to bring it toapproximately the speed of the newspaper press with which the device isassociated. The roll I2 is brought up topress speed by a wheel I8 havinga covering l9 of rubber or some similar material. The wheel i8 iscarried by an arm 20 and driven from a bevel gear 2! operated'by aflexible drive 22 from the newspaper press and in such manner that whenthe wheel 18 is in contact with an end of the paper roll 12, .it willbring the latter up approximately to press speed or at the rate of speedthat the web l5 travels in the normal operation of the press.

The arm 28 is pivoted on a shaft 23 and a bent arm 24 is connected tothe outer end of the arm 2!! by a bolt 25 which slides in one of thearms, a coil spring 25 being interposed between these arms. The wheel i8is moved into engagement with the end of the roll l2 adjacent theperipheral surface thereof substantially as shown and at this time theroll i2 is spaced a short distance from the guide roll 65a. It will beobvious that in this manner the roll 52 is very quickly rotated so thatthe web thereof isv moving at approximately the traveling speed of theweb 15 in the normal operation of the press.

The web from the roll 12 is connected to, the v web l5 by adhesiveapplied to the end of the fresh roll and preferably adhesive is appliedas indicated at 21 on Figure -6, the zig zag line affording more secureadhesive connection with the web I 5. It is desirable that as soon astheroll I2 is brought up to press speed that it be advanced so that theadhesive 21 can engage the web l5 so as to allow the newspaper press tocontinue uninterruptedly. For that purpose, the reel motor IE isenergized substantially when the new roll I2 attains press speed. Thisis accomplished in an exceedingly simple manner as will now appeal. Atiming strip 28 preferably of some material like Celluloid and of a sizeand shape simulating a banjo pick, having, as indicated, a substantiallypointed end, is inserted between the convolutions of the roll I2adjacent the peripheral end portion and substantially in alignment withthe adhesive strip 21.

For convenience of the operator, the fresh or oncoming roll is usuallyallowed to come to rest and in its balanced condition, the line ofadhesive 2! is applied and then the timing piece 28 is inserted in suchmanner that a portion thereof projects beyond the end of the roll and asubstantial portion is disposed between the convolutions of the roll. Itshould be understood that the line of adhesive 21 can be applied anyplace along the roll although from the standpoint of convenience, theoperator will usually permit the roll first to come to rest. The timingpiece 28 should project far enough beyond the end of the roll to contacta timing switch arm 29 which is pivoted in a housing 30 and in itsnormal position hangs downwardly substantially as shown on Figure 4.

The inner end of the arm 29 carried a contact strip 30a engageable witha contact strip 3| which acts as a stop, the outer end riding along astrip 32 which frictionally engages and holds the strip 30a in normalposition. The contacts lead from the strips 30a and 3| to a solenoid 59controlling the operation of the reel motor I6 and the arrangement issuch that when the arm 29 is swung outwardly or to the position shown inFigure 5 in which the contact is broken, the solenoid operates in suchmanner when the paster control button is depressed as to energize themotor I6 until the paster control button is released, to advance thereel in a clockwise direction (Figure 4) moving the roll I2 to theposition of the roll I4 shown on Figure 1, thus bringing the line ofadhesive 21 into contact with the web I5 at the proper time and splicingthese webs together. The swinging of the timing switch arm 29 to breakthe contact is caused by the timing piece 28 which moves into contactwith the free end of the arm as the roll I2 rotates and then passesunder it allowing the arm 29 to swing back by gravity to its normalposition. The timing piece 28 remains in place until the roll has beenunwound to free it when it is thrown or drops from the roll.

Reference is hereby made to our co-pending application, Serial No.167.100 for the details of operation of the driving wheel I8 and the websevering means by which the web I5 is out between the exhausted roll I 4and the roll I2 substantially at the time when the pester or splicing ofthe webs is accomplished. The severing of the web from the exhaustedroll can be accomplished in accordance with the disclosure in theco-pending application whereby the pastel can be effected withoutinterrupting the normal operation of the press. Details of constructionand operation of these parts form no part of the present invention sothat additional description and illustration is not considerednecessary.

The arrangement is such that when the driving wheel I8 is in operativedriving relation to the paper roll, the switch mechanism is away fromthe roll and conversely, when the switch mechanism is in operativeposition, the driving wheel I8 is disposed in inoperative position. Forthis purpose the switch housing is carried by a bracket arm 33 which ispivoted at to a portion of the bent arm 24. The arm 33 is connected by alink 35 to an extension 36 of the wheel carrying arm 20. An inspectionof Figure 2 will show that when the parts are in the full line position,the wheel I 8 is away from the paper roll but the switch mechanism isdisposed close to the end of the roll in position to be engaged by theactuator or timing piece 28. On the other hand, when the parts are inthe dotted line position, the wheel I8 is in operative driving relationto the paper roll but the switch mechanism is swung away from the rollto inoperative position.

From the above description, it will be apparent that the sequence ofoperations is as follows: adhesive is applied in any position selectedby operator on the next succeeding roll of paper or the roll which is tobe applied or connected to the traveling paper web preferably in themanner shown in Figure 6. Then the timing or Celluloid piece 28 isinserted near the periphery of the roll and between the convolutionsthereof substantially in line with the adhesive strip. When the operatorconsiders that it is time to make a pastel, the driving wheel I8 whichis constantly rotating at approximately press speed is moved intoengagement with the end of the roll thus driving the roll at pressspeed. As more fully described in our co-pending applicationhereinbefore mentioned, movement of the driving wheel I8 to roll drivingposition is effected manually. as diagrammatically shown on Figure 8, bya handle 40 which is fixed to a shaft M. The

shaft 4! is suitably connected to rock an eccentric disc 42 which isfree to swing about its axis 43. Turning movement of the shaft 4| swingsan arm 44 which has a notched end 45, so that the latter engages a pin46 on the disc 42 and rocks the disc in a counterclockwise direction tothe position shown on Figure 8. When the eccentric disc 42 is in itsraised position, the pin 46 is engaged by one end of a latch arm 41which holds the same in place. As soon as the eccentric disc is engagedor latched by the arm 41. the handle 40 is released and the arm 44 dropsdownwardly to its normal position. As shown the arm 41 is pivotedbetween its ends and the opposite end carries the armature of a solenoid48. end which engages the eccentric disc 42 so that when the disc israised as above described, the bent arm 24 is likewise rocked to movethe driving roll I8 to driving position into engagement with the paperroll. By depressing the pastor button, which is indicated as 58 inFigure 8 the driving wheel I8 is swung, as set forth in our copendingapplication, away from the paper roll. By referring to Figure 8, it willbe apparent that by depression of the paster control button or switch50, the solenoid 4-8 is energized through the leads 5|, 52, 53 and 54,thereby rocking the latch 4'! in a counterclockwise direction andreleasing the eccentric disc 42. The disc 42 will then swing downwardly(counterclockwise) thus allowing the driving wheel I8 to swing bygravity away from the paper roll and to such position that the contactpiece 55 on the bent arm 24 bridges the spaced contacts 56. Thereuponthe switch mechanism, and particularly the timing The bent arm 24 has aroller 49 at one switch arm- 29, is moved into the path of revolvingmovement of the Celluloid piece 28 which strikes against the arm 28breaking the contact as; above mentioned and thus; through suitablemeans, the reel motor operates at the proper time to move the line ofadhesive into contact with the traveling web i5. The tail of the web isthen severed in any suitable manner and the poster is completed, whenthe roll i2 is in the position occupied by the roll- M (Figure l) andthe pastel button is released.

When the operator sees that the roll is substantially exhausted andshortly before web splicing is required, the driving wheel i8 is movedmanually into engagement with the paper roll to bring it to press speed,as above indicated and as particularly shown and described in ourcopending application. It is to be understood that upon actuating thehandle M! to bring the driving wheel 58 into operative position, aswitch 5'! is thereby closed to allow current to flow through lead 58 toa solenoid 59 and thence through lead 60, switch arm 29, contact strip3! and lead 54. Energizing of solenoid 59 moves the armature 5i upwardlyopening switch 62 and closing switch 53. As soon as the handle All isreleased, the switch 5'! is opened and current is then supplied to thesolenoid 55 through leads 5! and (i l, switch 53, lead 65 and thenthrough the solenoid 59, lead 6! and other connections above mentioned.The operator then presses the control or paster button 56, whereupon thedriving wheel I8 is released and the timing switch is moved intooperative position as above described. When the switch arm 29 has beenthrown outwardly, as indicated in Figure 5, so that the solenoid 59 isreleased, the reel motor it will revolve the paper rolls at the propertime until the operator releases the paster button when the pester iscompleted. In this connection, it will be apparent that upon closing theswitch or paster control 50, current passes to the reel motor Hi throughthe leads 5!, 52 and 65 through switch 62 (which has been moved to itsdotted line or closed position upon release of the solenoid 59), andthen through lead 6'! to the reel. From the reel motor 16 current flowsthrough lead 68, contacts 56 and contact piece 55, lead 69 and lead 54.Obviously, in absence of an automatic tail severing device, the speed ofthe press must be reduced to afiord the operator sufficient time tosever the tail by hand but the use of an automatic tail severing deviceas shown in our co-pending application will enable the paster to beaccomplished without reduction in press speed.

One advantage of the above pastor is that an unskilled person can applythe adhesive to the paper roll and insert the timer piece. This is adecided improvement on similar devices which require that the adhesivebe applied at a certain place and ordinarily requiring the services oftwo men, one to hold the roll and the other to apply the adhesive.

It is to be understood that numerous changes in details of construction,arrangement and operation may be effected without departing from thespirit of the invention especially as define in the appended claims.
